This. Intel states max 1.3625VCore for 45nm chips so 1.44V is much too high for an E5300 24/7 and will degrade your CPU quickly. Try to max out the oc at 1.3625V and under 75C full load. Takes time yes, but saves power and lowers heat.
That being said if you're going to upgrade in a year and don't plan on selling the E5300, I wouldn't worry too much about it.
2.6.1 Absolute Maximum and Minimum Ratings
Table 3 specifies absolute maximum and minimum ratings only and lie outside the
functional limits of the processor. Within functional operation limits, functionality and
long-term reliability can be expected.
At conditions outside functional operation condition limits, but within absolute
maximum and minimum ratings, neither functionality nor long-term reliability can be
expected. If a device is returned to conditions within functional operation limits after
having been subjected to conditions outside these limits, but within the absolute
maximum and minimum ratings, the device may be functional, but with its lifetime
degraded depending on exposure to conditions exceeding the functional operation
At conditions exceeding absolute maximum and minimum ratings, neither functionality
nor long-term reliability can be expected. Moreover, if a device is subjected to these
conditions for any length of time then, when returned to conditions within the
functional operating condition limits, it will either not function, or its reliability will be
Although the processor contains protective circuitry to resist damage from static
electric discharge, precautions should always be taken to avoid high static voltages or
"Functional operation condition limits" = VID 0.8500~1.3625V - Table 4
"Absolute maximum and minimum ratings" = â€“0.3~1.45V - Table 3
To put it simply below 1.3625V is safe, between 1.3625 and 1.45V will degrade the chip, and above 1.45V is suicide.Edited by qiqi1021 - 3/4/11 at 8:55pm
